Abstract

A new electron cyclotron emission imaging (ECEI) diagnostic system is implemented on the DIII-D tokamak. This design makes use of technologies successfully demonstrated on the TEXTOR and ASDEX-UG tokamaks, while incorporating new features to provide enhanced flexibility and improved operation. The diagnostic makes use of a dual array configuration, allowing for simultaneous imaging of both the low and high field sides of the plasma, and is fully operational during electron cyclotron resonance heating (ECRH). Additionally, the highly flexible optical design allows for automated remote control of the vertical plasma coverage and resolution, focal plane location, and radial plasma coverage.
